i am going to use the following schedule from Colour de Verre100 dph.........................................300 degrees..................................hold 30 mins
150 dph.........................................1250 degrees................................hold 30 mins
150 dph.........................................1350 degrees................................hold 5 mins
Full...................................................900 degrees..............................hold 60 mins
100 dph...........................................600 degrees..............................off
Using 2 pieces of 3mm white glass 6 1/2 inches square which I will slump afterwords. Just an attempt to get all the temperatures right before I do a piece with prettier glass for the open house at Shapers. The glass came out with one big bubble so the pattern on the rest was thin to say the least. I am prefiring it now to see if that results in a better product.
Also trying to figure out how to best label my blog so I can call back entries to help me when I am doing this project in the future.
So then I am going to slump the fused white glass on the botanical pattern fuser onto this slumper mold using the following suggested firing schedule:
300 dph...................................1200 degrees......................................hold 5 mins
Full............................................900 degrees......................................hold 1 hour
100 dph......................................700 degrees......................................-0-
Full...............................................70 degrees......................................off
Following the top firing schedule the piece came out again with a huge bubble. What was I to do. Called up Coleur de Verre and asked for help on their botanical pattern fuser. Boy were they helpful. And the guy I spoke to one, one of the owners I believe, suggested less heat work and explained how different colors and viscosity effected the final piece. So I used his suggestions and took a smaller piece of the glass that I wanted to use. He had also talked about using more glass but I was not going to use the whole surface. I fired it at the following schedule and it worked for the most part but with a little pulling on the sides. So now I fired my two pieces of glass prior to putting it on the fuser and that came out well except that it picked up slight imperfections in the shelf below even though I had covered it with thin fire paper. But I am putting it on the botanical pattern fuser none the less and firing it with the following schedule. Hope this works or I will be wasting a nice piece of glass:
100 dph..........................300 degrees .......................hold 30 mins
150 dph...........................1250 degrees......................hold 30 mins
150 dph............................1325 degrees (this is 20 degrees lower than the lowest suggested processing temp)............................................hold 5 mins
Full...........................................900 degrees............................hold 60 mins
100 dph.................................... 600 degrees............................off
And this schedule is for a 6 1/4 square piece.
